Infinite range solar powered electric bike without a charge controller?

Testing a concept solar powered ebike without a charge controller. The result was surprising!

[@ms.gearhead6884]

You need a longer tongue for your trailer so you can mount the panel more forward. Your weight distribution will be better and you won't need 25lbs in the front of your trailer. Great experiment! It's something I was thinking of trying in the future

[@drewpaschal9294]

I am thinking this would be awesome as a rickshaw with the solar panel as the canopy.

[@JesseCataldo]

I've made one, you are correct. It's awesome :)

[@ricksummerfield784]

I would have tried a capacitor at the panel output , then a buck boost circuit to give the stable voltage, thank you for taking the time to make this video, i always looking forward to seeing your next videos

[@lyfebehyndbars9729]

Excellent demonstration of the usefulness of a solar panel on a mobile electric device! I really wish more companies would take solar as a supplement to the battery more seriously.

[@HansKeesom]

It is much easier just to charge a decent battery from an outlet. It also generates less drag

[@lyfebehyndbars9729]

@@HansKeesom yes I know, I’m not suggesting it as a replacement to the plug. I just really like the idea of having any kind of a vehicle that relentlessly keeps trying to trickle charge itself. Especially when I’m in the middle of nowhere. I would trade my glass roof on my car for a solar panel in an instant. I don’t care if it’s only like 5 ish miles a day. 5 miles is not nothing.

[@HansKeesom]

@@lyfebehyndbars9729 Theoretically I like to agree but the thing is costs : it is cheaper to buy a second or even third normal e-bike battery and put them in a panier instead of a trailer plus solarpanel plus charge controller etc. -weight : it is lighter to have a second or third battery then having a trolley and solarpanel -drag : you will have less drag with a second or third battery. The drag of the trailer is not likely compensated by the generated electricity....

[@pascalj4331]

it's up to trailer manufacturers to make it easier I think.

[@NimaSomeh]

its the wind lifting the nose of your solar panel at higher speeds, thats why its fish tailing. with some aero parts on the nose, it will perfect haha. great video

[@JackButlerVideos]

i wonder if you could use the battery as the weight on the trailer instead of carrying a dead weight that does nothing? Also where is this bike track? It looks great!!

[@robbyv.526]

Good thinking .... I like the idea

[@KENPlotbot]

Me too. All comments are great. I appreciate the way people can talk to each other without insulting.

[@closertothetruth9209]

with the new battery technology comming you wont need any power input for quite some time. many years ago on tv news a teacher drove a fibreglass buggy from one side of the usa to the other side using wind turbines, no internal combustion engine.

[@noreasonwhynot4548]

Fascinating experiment.

[@doctorlefthandthread]

You are a genius sir

[@dannystrachan475]

Nice idea...how about using 2 smaller panels with a pitch in the center. You'll never get full power on both but a lot more on the one facing the sun. No matter the direction of the sun or the direction you're traveling in, you will capitalize on higher input from one panel because of the better angle. At noon it will be a compromise but still have a high enough input. Second option is a smaller pitch with 2 different sized panels. Good luck...

[@KENPlotbot]

Mindblowing sir! Your bike looks like a laboratory =)

[@xiaoka]

Awesome. Now do a sun tracking actuated panel! 😅

[@carscoffee5263]

Very interesting indeed sir...

[@sshutupurface8345]

make solar tracker on the back, so your panel can move to correct angle of sun

[@sshutupurface8345]

very cool make us some more like a car from bicycle parts, super light

[@MarkSpohr]

Your solar panel should have a blocking diode in the panel itself so you don't need the extra external diode. As you note, charging the battery without a charge controller can overheat the battery and cause it to catch fire. Not a good idea.

[@pr5991]

Solar panels are itself a diode, you can’t back feed these, additionally most solar panels have built in diode

[@sshutupurface8345]

The big question is why are all vehicles not using this method? Firstly they too heavy, and if everyone rode bikes they would need alternatives when it rains a lot of the time, a simple covered road with battery change stations every mile, the charge stations are solar powered simple

[@davidsteinhour5562]

I really wish there were more options for all-in-one MPPT solar / Li-cell balance chargers. Everything I see is HVDC panel -> 12v output, and then you need an inverter to turn 12v DC -> 110AC and then a battery charger for -> HVDC again. It's silly.

[@ricksummerfield784]

Try putting a capacitor at the panels output, then connect a buck boost circuit to dial in whatever D.C. voltage you need

[@goojy]

can the ebike run and charge from the charger and do charger have charge controller i meen by that to found the safest way to charge wile on the go and discharge same time in a balanced way and did any one try wind generators with the solar on the roof so no fish tail same time ?

[@ssportslivetvstreaming]

I would love to go from all the way up from south to north america without any effort

[@gagank478]

If you are in California, I would love to get more information from you. I am wanting to build a solar powered ebike similar to yours but a little less weight. Would love your input!

[@MichaelFergusonVideos]

If you would disconnect the solar panel when you check the battery voltage, would it still be as high as your readings with it conntected?

[@jbar3337]

What if you use the second battery on the back to weigh it down where the weight is have the solar panel charging the second battery while you ride and then swap batteries out and start to charge on the first battery that was on the bike

[@robingoolsby6024]

so awesome!

[@ellenorbjornsdottir1166]

Wouldn't there be an issue with the panel dragging down the battery if the panel is outputting below its nominal voltage?

[@ellenorbjornsdottir1166]

oic, diode

[@manipulativer]

wouldn't you get better effeciency with an mppt? Instead of the weight for fishtail just plug a mppt?

[@peachsncream5808]

Why not move the axle to the back end of the trailer ?

[@Sylvan_dB]

Doesn't your battery have a BMS that will protect against overcharge? It seems likely... if so, that is essentially the same as the original solar charge controllers (before PWM).

[@tims8603]

Correct me if I'm wrong but your batteries have built in BMS. Wouldn't that stop charging before any damage? Drew Builds Stuff channel has a solar charging quad cycle you might like.

[@vuaeco]

The Kobalt 24V batteries have BMS. But it only protects the batteries if you use a Kobalt charger to charge it or a Kobalt tool to discharge it. It has no protection if you just tap into the (+) and (-) terminals.

[@tims8603]

@@vuaeco OK.

[@Sylvan_dB]

@@vuaeco Interesting. So no charge or discharge mosfets between the cell string and the terminals?

[@richie8214]

So I need a 2 or 3 amp dc charge controller ?

[@Idahomie]

What gonzo set -up.

[@Idahomie]

Next vid will be from your local hospital...pleeze use both hands.

[@robbyv.526]

oh man ..... I absolutely loved In and Out burger you lucky dog . From WA ..... no In and Out .... mo like Down And. Out. = /

[@JohnClulow]

sell your house and move closer to in-N-out burger so you can just walk

[@vuaeco]

Great idea!

[@JohnClulow]

please record and post the video of your move.

[@JohnClulow]

I wanna see, "I can walk over to in-and-out Burger now without no damn lithium ion batteries on me.

[@vuaeco]

@@JohnClulow I can walk there even now but Li-ion batteries are always on me.

[@JohnClulow]

Love your videos, man... keep 'em comin !!@@vuaeco

[@pascalj4331]

These are very strange results. Your solar power outputs 54.7v, but manages to charge a battery that is at over 60v. This is not supposed to conform to physics. Open circuit voltage, as I understand it should not be dangerous if no current is supplied, and especially not if it matches full state of charge of battery. However, I don't understand your video/measurements possibilties, and one explanation is that I don't understand electricity.

[@peteleoni9665]

So...are you pedal assisting or all motor?

[@vuaeco]

The answer is at 3:48

[@mefirst4266]

1. I THOUGHT YOU WERE A ELECTRICAL ENGINEER. NOW I KNOW YOUR NOT. 2 . WHY WOULD I WANT TO PULL 2 SOLAR PANELS AROUND... TOTALLY CLICK BAIT ...

[@Jasonoid]

Why all caps?

[@biomangarance4878]

Excellent, why don't you put a roof with the solar panel? 👏👏👏👍

[@smoxesk]

ther are much easier ways then that , man has too catch up too this day and age. but i will say this is superb am shocked you pulled this off not saying i can build this setup. great work great video

[@truthministries77]

What are the easier ways?
